@olflappy all these have been done in research. In one case they even resliced the model on the go, based on the height error (from a laser profilometer). They had something like an rtx2070 doing the online reslicing lol. It was a BAAM printer though. All of these things are great in theory, but making them viable in practice and on any printed geometry, not just some research test-sample rectangular block, is a whole different issue.
Also photogrammetry was also investigated. It sucks. Structured light projection, speckle patterns and laser profilometers are all miles better.
